So I got a friend who can't connect, others can, he set up his own server to test, he can't connect to that, he's in the Netherlands, I can provide the ip if needed, but if it's a known thing then there is no need.
What steps should we take? I can't use /pardon-ip as that is for the server itself, it's like the whole ip is blocked, as it doesn't show him the server being online.
Can anybody help?
